Never shot Marbs....what bore size do you use?

[Skoad]

Looking to move up a notch from the Big Ball, to marbs....but not sure what size bore of barrel i will need to shoot these well.

Tell me what you use

My kid uses a .685" in his 'cocker, I use a .687" in my E-Mag, and an Armson SSR in my classic. That barrel has straight fluteing, and is "small bore" (.685"ish)

Marbs, All-Star, El Tigre, Slam, they all seem the same to me, and I like 'em all!

k, so i guess a 689 and a 685 should cover me pretty well.

CP barrels here i come!

0.691... best all round bore size in my experience
